My "new" '74 Duster- or why I need a project like a hole in the head
Here are some pictures of the vents. On the drivers side, its just to the left of the parking brake. 3 nuts hold it onto the lower cowl, two I highlighted in the picture. That gives you access to the cowl space.
On the passenger side, you have to remove the front of the heater box. Once off, it gives you access to the cowl space which I highlighted. First picture is from below, second picture is through the glove box. You'll need to pull the glovebox liner to make it work on the passenger side.
